Re: \i and \watch

Thanks for the explanation.
Yeah, here's what's happening. So, yeah, we'll check on having to script it
instead.

###
=> select now() ;
now
-------------------------------
2024-11-07 07:46:23.876888+00
(1 row)

=> \! cat x.sql
select version() ;
=> \i x.sql
version
--------------------------------------------------------------------------------------------------------------
PostgreSQL 14.12 on aarch64-unknown-linux-gnu, compiled by
aarch64-unknown-linux-gnu-gcc (GCC) 9.5.0, 64-bit
(1 row)

=> \watch 5
Thu 07 Nov 2024 20:47:05 NZDT (every 5s)

now
-------------------------------
2024-11-07 07:47:05.411747+00
(1 row)

Thu 07 Nov 2024 20:47:10 NZDT (every 5s)

now
